BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to surveillance camera systems, and more particularly to an adjustable surface-mountable support for a surveillance camera that provides for a wide range of adjustability while providing protection for the wires passing through the interior thereof.

2. Description of the Prior Art

The use of surveillance cameras has become increasingly widespread. Often, such cameras must be mounted outdoors where they may be subjected to dramatic temperature, moisture and other climactic changes, as well as potential vandalism. Accordingly, different enclosures and support structures have been developed for surveillance cameras. Unfortunately, the designs of many existing support structures allow the wires leading from the camera to be exposed to the outside where they can be damaged or cut. In addition, many existing camera supports cannot support large cameras and provide only a very limited range of adjustment of the position of the attached camera.

It is therefore desirable to provide an adjustable support structure for a large surveillance camera that is resistant to water and moisture penetration and protects the wires connected to the camera while providing a wide range of adjustable viewing angles for the attached camera.

SUMMARY OF THE INVENTION

The present invention provides a superior sealed aesthetically pleasing surveillance camera support structure that maintains the camera wires on the inside, and provides wide range of positioning and viewing angles even when a large or heavy camera is attached. The invention includes a surface-mountable base and a reinforced outwardly-extending support arm. A specially adapted rotatable swivel mechanism is attached at the end of the arm that is capable of being rotated (the panning or scanning angle) through a horizontal arc of as much as approximately 300°. Adjacent to the swivel is another rotatable joint that is capable of moving up and down (the tilt angle) through an arc of as much as approximately 180°. A camera support platform is attached above the rotatable joint.

The support structure is designed so that once the viewing angle for the camera is selected, the swivel and joint are tightened so that the camera remains pointing at this fixed angle. In order to accommodate larger cameras, significant bearing surfaces are provided in the swivel and joint so as to maximize the frictional resistance to movement. At the same time, sufficient space is provided inside both the swivel and joint to allow wires leading from the camera to pass through. Wires exiting the camera pass through the support platform, rotatable joint, swivel, arm and base into an opening provided in the surface behind where the mount is attached.

The present invention also allows considerable adjustability and flexibility with respect to establishing and changing the viewing angle of the attached camera, while keeping the sensitive internal components shielded from outside contaminants. Establishing and changing the viewing angle is accomplished by loosening the tightening screws of the swivel and/or joint, moving the camera to the desired angle, and then retightening these screws.

It is therefore a primary object of the present invention to provide an adjustable surface-mountable support apparatus for a surveillance camera that is resistant to water and moisture penetration and protects the wires connected to the camera while providing a wide range of adjustable viewing angles for the attached camera.

It is also an important object of the present invention to provide an adjustable surface-mountable surveillance camera support that may be horizontally adjusted through as much as 300° and vertically adjusted through as much as 180°.

It is also an important object of the present invention to provide an adjustable surface-mountable surveillance camera support that is capable of being adjusted through a wide range of possible viewing angles and then firmly secured in a selected fixed position.

It is also an important object of the present invention to provide an adjustable surface-mountable surveillance camera support that is capable of supporting a large, heavy surveillance camera in a fixed position.

It is also an object of the present invention to provide an aesthetically pleasing yet durable and reliable support structure for a surveillance camera.

Additional objects of the invention will be apparent from the detailed descriptions and the claims herein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the drawings wherein like reference characters designate like or corresponding parts throughout the several views, and referring particularly to FIGS. 1 and 2, it is seen that the support structure of the present invention includes a surface-mountable base or plate 11 for attachment to a flat surface such as a wall, ceiling, soffit or shelf; a hollow reinforced arm 12 fixedly attachable to mounting plate 11; a rotatable member 34 for adjustable engagement with a socket 21 at the end of arm 12; and upper journal member 40 for adjustable engagement with the rotatable member 34; and an upper platform 19 for holding the surveillance camera. Hollow or open areas are provided in side each of these members to allow wires 15 to be threaded through on the inside from the mounting surface to the camera

Referring to FIGS. 3-5, it is seen that a socket 21 is provided at the end of arm 12 for engagement with a mating structure 30 on a separate rotatable member 34. Socket 12 includes an upwardly extending annular lip 22 having an outer angled bearing surface 23 as shown in FIG. 4. A through hole 25 is provided in the center of socket 21 for receiving an attachment means such as a screw 26. An open interior area 24 is provided at the bottom of socket 21 that is in communication with the hollow interior 13 of arm 12 through which one or more wires 15 may be threaded. See FIGS. 6-8 for wiring.

Rotatable member 34 includes a bell-shaped lower journal section 30 having an angled annular interior surface 31 for slidable engagement against surface 23 of socket 21 as shown in FIGS. 4 and 5. A receptacle and opening 29 is provided at the center of journal section 30 for receiving attachment screw 26, which also provides a pivot for rotation of member 34. An open interior area 38 is provided in journal section 30 for receiving one or more wires 15. Journal section 30 is inserted over socket 21 and rotated to a desired location, as surfaces 23 and 31 bear against each other. When the desired position is reached, screw 26 is tightened in order to fix this position. The area of surfaces 23 and 31 is deliberately large to provide sufficient friction to hold a heavy camera in the selected position.

The upper portion of rotatable member 34 includes a hemispherical cup 35 having an axis that is perpendicular to that of bell-shaped journal section 30. The interior of cup 35 includes annular angled bearing surface 36 for receiving a journal member 41 of an upper support. A through hole 45 is provided in the center of cup 35 for receiving an attachment means such as a screw 43. Open interior area 38 opens into cup 35 providing a channel between journal section 30 and cup 35 through which one or more wires 15 may be threaded.

An upper support member 40 is provided for holding the surveillance camera of the system as shown in FIGS. 3 and 5. Support member 40 has a lower journal member 41 in the form of an annular lip having an angled bearing surface 44 for slidable engagement against surface 36 of hemispherical cup 35 of rotatable member 34. An opening 42 is provided at the center of journal member 41 for receiving attachment screw 43 which also serves as a pivot for rotation of journal member 41. An open interior area 48 is provided in journal member 41 for receiving one or more wires 15. Area 48 provides a channel to the interior of upper platform 19 so that wires 15 may be threaded to the camera. See FIG. 7 Journal member 41 is inserted into cup 35 and rotated to a desired location, as surfaces 44 and 36 bear against each other. When the desired position is reached, screw 43 is tightened in order to fix this position. The area of surfaces 44 and 36 is deliberately large to provide sufficient friction to hold a heavy camera in the selected position.

Some exemplary tilt angles for the camera are illustrated in FIGS. 9 and 10. FIG. 9 shows a camera enclosure 18 tilted straight down, a full 90° from the horizontal axis of the arm 12. FIG. 10 shows the same enclosure tilted upward at about 6°. It is to be appreciated that a large camera enclosure 18 is shown in these illustrations, and that smaller enclosures will allow for a much wider range of tilt angles, up to a full 180°.

FIG. 11 shows a rotation (pan or scan) angle using the same large camera enclosure 18 with viewing window 17. Even with the large enclosure 18 as shown, the counter-clockwise range of rotation is about 159°(180°−21°) from the angle of arm 12. The same range of rotation (about 159°) is available in the clockwise direction, for a full range of well over 300°. Again, it is to be appreciated that a large camera enclosure 18 is shown in FIG. 11, and that smaller enclosures will allow for an even wider range of rotation (pan/scan) angles.
